GAS-STOVE.

SPECIFICATION forming part Of Letters Patent N0 276,302, dated. April 24, 1883.

` Application filed April 18, 1881. (No model.)

lTo all whom it may concern:

`gas-stoves, in which the heat produced by the burning gas is increased by heating thc gas and the air `with which it is to burn by the products ot' combustion before they cnter the combustion-chamber. Y

My invention will be clearly understood from the accompanying drawing, in Which A represents generally an inclosed casing containi ing the operative parts of my apparatus.` The casing is divided generally into two chambers,

B and F, which are separated from each other by a horizontal partition, K, extending almost to the forward end ot' the chamber. The two chambers, B and F, communicate with each other by the passage L at the end of the partition K. The combustion occurs in the chamber B, the gas to be burned in said chamber being supplied by the pipe D, which passes in through the chamber F, and then returns and enters thechamber B by the nozzle H, as is clenrlyshown. The air to supportsaid combustion enters by the pipe C, which also passes through the chamber F and enters the combustion-chamber B by the nozzle G, asis clearly shown. The lower chamber, F, communi- Cates directly with the chimney L. By means of this chimney the products of combustion are drawn oft' and a draft is secured.

The operation of my apparatus can now be readily understood. Gas having been admittedto the pipe D by means of the stop-cock M escapes into the combustion-chamber B, as before described. The air tosupport this combustion, which may be regulated by a damper, y

E, meets the gas at the orifice G,andthecom bustion occurs in the chamber B. The products of combustion by the draft in the chimney L are returned through the lowery chamber, F, and passed over'the pipes D and C, thereby thoroughly heating the same. As a result`of this preliminary heating of the gas and air before they arrive at the point of combustion,a much more thorough burning of' the gas is effected, and a much higher temperature is produced, while at the same time thc injurious prod ucts of combustion are removed from the chamber Where the apparatus is placed.

The apparatus as shown is simple in construction and very inexpensive to make,and its advantages will be apparent on inspection.

What I claim as myinvention, and desire to secure by Letters Patent, is-

' In agas-stove, the combination of the combustion-chamber B, located above and separated bya horizontal partition from the chamber F, through which theproducts of combustion pass to the chimney L, and the pipes D and 0, for supplying gas and air to the combustion-chamber B, which vpass horizontally through the chamber F, and then return and deliver into the combustion-chamber B, substantially as described.
